Submitted on 3/3/2024 | Answered by Vandana Rana

Answer :

Firstly, we subtract the remainder 5 and 8, respectively, from corresponding numbers and then get the HCF of the resulting numbers .After removing these remainders from the numbers, we have:


(70 − 5) = 65


(125 − 8) = 117


Now, the required number


117=13×3×3


65=13×5




∴ HCF = 13.
Thus, 13 is the largest number which is divisible by 70 and 125 leaving remainder 5 and 8.
